本発明は鉄道車両用台車とその歯車装置に関するもので
、特に高速鉄道車両用として好適なものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bogie for a railway vehicle and a gear device thereof, and is particularly suitable for use in a high-speed railway vehicle.

質量と呼んでいる。(Prior Art) In general, the relationship between the wheels and the car body of a railway vehicle is such that an axle that holds the wheels is supported by a bearing, and a bogie elastically holds this axle bearing via an axle spring. A pillow spring is inserted between the bogie and the vehicle body, and the bogie elastically holds the vehicle body via the pillow spring. Among these parts, parts such as wheel axles that directly load the rail and are not supported by the shaft springs are called unsprung masses, and parts such as the bogie frame and the main electric motor attached to it are supported by the shaft springs. The part is called the sprung mass, and the part supported by the pillow springs, such as the car body, is called the sprung mass.
高速鉄道車両においては、著しく大きい輪重や横圧を低
減することが軌道保守の軽減や列車走行の安全確保のた
めに望ましいので、ばね下質量を軽減することが行われ
ている。In high-speed railway vehicles, it is desirable to reduce significantly large wheel loads and lateral forces in order to reduce track maintenance and ensure train running safety, so the unsprung mass is reduced.
即ち、過去において鉄道車両が比較的低速で走行してい
た時代には、主電動機は車軸に懸架されてばね下質量が
大きかったが、現在の我が国では主電動機は台車に装架
してばね間質量とすることが一般に行われている。In other words, in the past, when railway vehicles ran at relatively low speeds, the traction motor was suspended on the axle and had a large unsprung mass, but today in Japan the traction motor is mounted on a bogie and has a large unsprung mass. Generally speaking, it is defined as mass.

は平面図、（ｂ）は正面図、（Ｃ）は側面図である。However, in high-speed railway vehicles, it is desirable to further reduce the mass between the springs by mounting the main electric motor on the car body in terms of vibration ride comfort and high-speed stability. However, as an example, a method of suspending the main motor from the vehicle body will be explained with reference to FIG. Figure 2 is a diagram showing the main parts of the motor equipment, (a)
is a plan view, (b) is a front view, and (C) is a side view.
第２図において、主電動機１は台車側と車体側とへ支持
されるように両側への支持腕を持ち、台車側へは台車枠

される。かくして、リンク５は車体と主電動機１との間
でピン４の軸を中心とした回転と共に、ピン４を含む平
面上をある程度回転する自由度が与えられている。In Fig. 2, the main electric motor 1 has support arms on both sides so as to be supported by the bogie side and the car body side, and is connected to the bogie frame 2 via a pin 3 to rotate around the axis of the pin 3. The main electric motor 1 is supported by a link 5 via a pin 4 fixed to a support arm of the main electric motor l. A link 5 whose one end is supported by a pin 4 by a spherical bearing 7
The other end is connected via a rubber bush 16 to a pin 15 supported by a bearing 17 on a support base 6 fixed to the vehicle body. Thus, the link 5 is given a degree of freedom to rotate about the axis of the pin 4 between the vehicle body and the main electric motor 1 and to rotate on a plane containing the pin 4 to some extent.
このようにして、主電動機１は台車に対しては相対上下

台車枠２に支持されて、動力伝達時のトルク反力を受け
る構造になっている。In this way, the main electric motor 1 is supported so that it can only move up and down relative to the truck, and can move up and down relative to the vehicle body as well as rotate by steering the truck. The power of the traction motor 1 supported in this manner is transmitted via the flexible joint 11 to the gearing 12 and from there to the axle 14. The gear device 12 has a large gear portion supported by an axle 14, and the opposite side supported by the bogie frame 2 by a suspension device 18, so as to receive a torque reaction force during power transmission.
〔発明が解決しようとする課題］
従来の鉄道車両用台車は前述の如く歯車装置の一方を吊

い量が増大し、従来主電動機を台車に装架していた場合
に使用していたたわみ継手の許容偏角内に押えるために
は、たわみ継手の軸方向寸法を長くする必要がある。[Problems to be Solved by the Invention] As mentioned above, in conventional railway vehicle bogies, one side of the gear device is supported on the bogie frame by a hanging device, so there is a problem with relative vertical movement such as deflection of the pillow spring between the bogie and the car body. Due to movement, the amount of misalignment between the output shaft of the traction motor and the pinion shaft, which is the human power shaft of the gear system, increases, and the allowable deflection angle of the flexible joint used when the traction motor was conventionally mounted on a trolley increases. In order to hold it inward, it is necessary to increase the axial dimension of the flexible joint.
又、主電動機の質量を車体で負荷する割合を多くするた
めに、車体に懸架する位置を主電動機の中心に近付ける

置が車輪のバックゲージ内に収まらな（なる欠点があっ
た。In addition, in order to increase the proportion of the mass of the traction motor carried by the vehicle body, the closer the suspension position to the vehicle body is to the center of the traction motor, the more the vertical misalignment between the output shaft of the traction motor and the pinion shaft of the gear system. The problem was that the space for the flexible joint became too long, making it impossible for the power transmission device to fit within the back gauge of the wheel.
〔課題を解決するための手段］
本発明は前述の欠点を解消するために、歯車装置の車軸

である。[Means for Solving the Problems] In order to solve the above-mentioned drawbacks, the present invention suspends the side of the gear device opposite to the axle by the main motor, so that the output shaft of the main motor and the pinion shaft of the gear device can be connected to each other. This aims to reduce the amount of misalignment and shorten the axial dimension of the flexible joint.
即ち、本発明による鉄道車両用台車は、鉄道車両用主電
動機を一方では側部で相対上下運動のみを吸収できる手
段により台車に支持せしめ、他方では軸芯を含む鉛直面
付近で相対上下運動と共に台車の舵取りによる回転変位
をも吸収できる手段により車体に支持せしめる如く構成
すると共に、歯車装置の吊り装置を前記主電動機で支持
するよう構成したことを特徴とするものである。That is, in the railway vehicle bogie according to the present invention, the main electric motor for the railway vehicle is supported on the bogie by means capable of absorbing only the relative vertical motion on the side portions, and on the other hand, the railway vehicle main motor is supported on the bogie by means capable of absorbing only the relative vertical motion in the vicinity of the vertical plane including the axis. The present invention is characterized in that it is configured to be supported on the vehicle body by means capable of absorbing rotational displacement due to steering of the truck, and also configured to support the suspension device of the gear device by the main motor.
又、本発明による鉄道車両用歯車装置は、該歯車装置の
吊り装置の歯車装置側の吊り受部をピニオン軸中心に設
けたことを特徴とするものである。Further, the gear device for a railway vehicle according to the present invention is characterized in that the suspension receiving portion on the gear device side of the suspension device of the gear device is provided at the center of the pinion shaft.
そのために、歯車装置の大歯車部を車軸に支承し、反対
側を吊り装置により主電動機で支持するように、主電動
機枠又は端蓋から歯車装置のピニオン軸の真上まで伸ば
した吊り受部を構成し、且つ主電動機枠の軸中心に近い
位置を、両端部が球面軸受等で回転自在なリンクで車体
から懸架するよう構成する。For this purpose, a suspension support part extends from the main motor frame or end cover to just above the pinion shaft of the gear apparatus, so that the large gear part of the gear apparatus is supported on the axle shaft, and the main motor is supported by a suspension apparatus on the other side. The main motor frame is configured to be suspended from the vehicle body at a position close to the shaft center by a rotatable link with spherical bearings or the like at both ends.
又、歯車装置の吊り装置の歯車装置側の支持部は、回転
自在な球面軸受等によりピニオン軸中心部に構成する。Further, the support portion of the gear device suspension device on the gear device side is constructed at the center of the pinion shaft using a rotatable spherical bearing or the like.
本発明による鉄道車両用台車は前述の如く、歯車装置の
ピニオン軸中心を主電動機から吊るように構成されてい
るため、車体及び台車の上下運動による主電動機の出力
軸中心の上下動と、歯車装置のピニオン軸中心の上下動
とはほぼ同し値になり、上下方向の芯違い量は僅かの値
ですむ。As described above, the railroad vehicle bogie according to the present invention is configured such that the center of the pinion shaft of the gear device is suspended from the main motor. The value is almost the same as the vertical movement of the center of the pinion shaft of the device, and the amount of misalignment in the vertical direction is only a small value.
従って、主電動機の出力軸中心と歯車装置のピニオン軸
中心との芯違い量は、トルク伝達時の歯車装置の吊り装
置の吊りゴムの撓みと、主電動機が車体上下動時に台車
側支持部を中心に回転することにより台車方向に前後に
若干移動するのに対し、歯車装置が主電動機の上下動に
より車軸を中心に回転しピニオン軸が車軸方向に前後に
若干移動することによる前後方向の芯すれと、車軸が台
車枠に対し７て動く前後動静の芯ずれと、及び前述の上
下方向の僅かな芯すれとの合成値となり、芯違い量は従
来に較べて大幅に小さくなる。Therefore, the amount of misalignment between the center of the output shaft of the traction motor and the center of the pinion shaft of the gear device is determined by the bending of the hanging rubber of the suspension device of the gear device during torque transmission, and the amount of misalignment between the center of the output shaft of the traction motor and the center of the pinion shaft of the gear device. The gear system rotates around the axle due to the vertical movement of the main motor, and the pinion shaft moves slightly back and forth in the direction of the axle. The amount of misalignment is a composite value of the misalignment, the longitudinal misalignment caused by the axle moving relative to the bogie frame, and the slight misalignment in the vertical direction mentioned above, and the amount of misalignment is significantly smaller than in the past.
そのため、たわみ継手の軸方向寸法が短くても許容偏角
内に収めることができる。Therefore, even if the axial dimension of the flexible joint is short, it can be kept within the allowable deviation angle.
又、主電動機を車体に懸架する位置を主電動機の真上に
近付けても、主電動機の出力軸と歯車装置のピニオン軸
との芯違い量はほとんど増加しないので、主電動機の軸
芯を含む鉛直面付近で主電動機を車体に懸架して、主電

を吊り装置で台車枠に懸架して歯車装置質量の一部をば
ね間化していたものが、本発明による鉄道車両用台車の
場合にはばねと化される効果がある。In addition, even if the position where the traction motor is suspended on the vehicle body is moved closer to directly above the traction motor, the amount of misalignment between the output shaft of the traction motor and the pinion shaft of the gear system will hardly increase, so the amount of misalignment between the output shaft of the traction motor and the pinion shaft of the gear system will hardly increase. The traction motor is suspended on the car body near the vertical plane, making most of the traction motor's mass on springs, and in the past, the gear system was suspended on the bogie frame with a suspension device, leaving part of the gear mass on the springs. However, in the case of the railway vehicle bogie according to the present invention, there is an effect that the spring is turned into a spring.

第２図と同一の符号は同一機能を有する部分を示す。FIG. 1 is a diagram of an embodiment of a railway vehicle bogie and gear device according to the present invention, in which (a) is a plan view, (1)) is a front view with main parts sectioned as seen from the direction of travel, and (C) is a side view,
The same reference numerals as in FIG. 2 indicate parts having the same function.
主電動機ｌは台車枠２にピン３を介してピン３の軸を中
心として回転可能なように主電動機１を支持する２本の
支持腕１ａと、歯車装置１２の吊り装置１３を懸架する
ために主電動機枠１ｂから歯車装置１２のピニオン軸の
真上まで突き出した支基１ｃとを具えている。The main electric motor 1 suspends two support arms 1a that support the main electric motor 1 and a suspension device 13 of the gear device 12 so as to be rotatable about the axis of the pin 3 via a pin 3 on the bogie frame 2. The main motor frame 1b is provided with a support base 1c that protrudes from the main motor frame 1b to just above the pinion shaft of the gear device 12.
又、主電動機１をリンク５により車体から懸架するため
に、リンク５の両端にそれぞれ球面軸受７が装入され、
これらの球面軸受７はそれぞれピン４を介して一方は支

。かくして、リンク５は両端に装入された球面軸受７に
より、車体と主電動機１との間でどの方向にも回転する
自由度が与えられる。Further, in order to suspend the main motor 1 from the vehicle body by the link 5, spherical bearings 7 are inserted at both ends of the link 5, respectively.
One of these spherical bearings 7 is mounted on the center line of the main motor shaft of the support base 1c via a pin 4, and the other is mounted on a support base 6 attached to the vehicle body via a buffer rubber 8. Thus, the link 5 is given the freedom to rotate in any direction between the vehicle body and the main electric motor 1 by the spherical bearings 7 installed at both ends.
更に、吊り装置１３の一端は球面軸受９を介して歯車装
置１２のピニオン軸中心位置に装着され、他端はこの球

同しく車軸１４に支承されている歯車装置１２が、車軸
１４の周りで回転可能なようにピニオン軸中心で吊り装
置１３により主電動機１に懸架される。Furthermore, one end of the suspension device 13 is attached to the center position of the pinion shaft of the gear device 12 via a spherical bearing 9, and the other end is attached to the above-mentioned support IC via a buffer rubber 10 at a position directly above the spherical bearing 9. A gear device 12, which is attached to the main motor and whose large gear portion is supported on an axle shaft 14 in the same manner as the gear device shown in FIG. 1.
このようにして、主電動機ｌは台車に対しては相対し下

し動きをするように台車と車体とによって支持され、主
電動機１の動力はたわみ継手１１を介して歯車装Ｗ１２
へ伝達され、更に歯車装置１２から車軸１４へ伝達され
る。In this way, the traction motor 1 can move downward relative to the bogie, and the rotational movement caused by steering the bogie is supported by the bogie and the car body so that it moves in the same manner as the bogie. The power is transmitted to the gear system W12 via the flexible joint 11.
from the gear system 12 to the axle 14.
吊り装置１３により主電動機１へ伝えられる歯車装置１
２のトルク反力は、吊り装置１３とリンク５とがいずれ
もほぼ主電動機１の軸芯上にあるため、そのままりンク
５を介して車体に伝えられて車体によって支持される。Gear system 1 transmitted to main motor 1 by suspension device 13
Since both the suspension device 13 and the link 5 are located substantially on the axis of the main motor 1, the torque reaction force No. 2 is directly transmitted to the vehicle body via the link 5 and is supported by the vehicle body.
なお、吊り装置１３とリンク５との主電動機軸芯上の位

１にモーメントが発生するが、２本の支持腕１ａにより
台車枠２でこのモーメントを受は止める。このことから
、リンク５は吊り装置１３にできる限り近付けた位置に
設置することにより、このモーメントを小さくできるこ
とは自明である。Note that since the positions of the suspension device 13 and the link 5 on the main motor axis are misaligned, a moment is generated in the main motor 1 when it receives a torque reaction force. So Uke stops this moment. From this, it is obvious that this moment can be reduced by installing the link 5 as close as possible to the hanging device 13.
本発明による鉄道車両用台車においては、台車が舵取り

るが、主電動機ｌをリンク５によって車体から懸架する
位置が、第２図に示した従来のものより台車の回転中心
位置に近くなっているので、リンク５の両端のずれは少
なくてすむ。In the railway vehicle bogie according to the present invention, the spherical bearings 7 are mounted on both ends of the link 5 even when the bogie makes a steering movement.
Due to the flexible connection, the link 5 suspends the main motor l from the vehicle body following the steering movement of the bogie. At this time, the main electric motor l moves in accordance with the rotational displacement of the bogie due to the steering movement due to the function of the pin 3 connected to the bogie frame 2, so that no displacement occurs in the distance from the gear device 12, which is the same as in the conventional case. However, since the position where the main motor l is suspended from the vehicle body by the link 5 is closer to the center of rotation of the bogie than in the conventional system shown in FIG. 2, the displacement between both ends of the link 5 can be reduced.
車体が台車に対して上下運動あるいはピッチング運動を
行う場合も、前述のリンク５の機能とビン３の機能とに
よって、主電動ｍ１は車体と台車枠の両者によって支障
なく支持されるが、歯車装置１２がピニオン軸芯を主電
動機１の軸の中心線上で吊り装置１３により懸架されて
いるので、主電動機１の上下動に伴ってピニオン軸の中
心がほぼ同じ量だけ上下動する。このため、主電動機ｌ
の出力軸中心と歯車装置１２のピニオン軸中心との上下
方向の芯違い量は極く僅かとなり、軸方向寸法の短いた
わみ板継手１１でも充分この芯違い量を吸収できる。Even when the car body performs vertical movement or pitching movement with respect to the bogie, the main electric motor m1 is supported by both the car body and the bogie frame without any problem due to the functions of the link 5 and the function of the bin 3 described above. 12 is suspended by the suspension device 13 with the pinion shaft core on the center line of the shaft of the main motor 1, so that the center of the pinion shaft moves up and down by approximately the same amount as the main motor 1 moves up and down. For this reason, the traction motor l
The amount of misalignment in the vertical direction between the center of the output shaft and the center of the pinion shaft of the gear device 12 is extremely small, and even the flexible plate joint 11 having a short axial dimension can sufficiently absorb this amount of misalignment.
又、主電動機軸中心線上をリンク５により車体に懸架し
ているため、主電動機質量のほとんどの部分が車体に負
荷されると共に、歯車装置１２も主電動機１で懸架して
いるため、従来台車に負荷されていた歯車装置１２のば
ね量分質量も車体に負荷することができる。In addition, since the traction motor is suspended from the vehicle body by the link 5 on the shaft center line, most of the mass of the traction motor is loaded onto the vehicle body, and the gear system 12 is also suspended by the traction motor 1, which makes it difficult to use conventional bogies. The mass of the gear device 12 that was previously loaded by the spring amount can also be loaded onto the vehicle body.
尚、吊り装置の歯車装置側は本実施例の如くピニオン軸

有効に活用することができる。Note that the same effect can be obtained by supporting the gear device side of the suspension device near the bottom of the pinion shaft instead of at the center of the pinion shaft as in this embodiment, but the suspension device becomes longer and the weight increases. This results in drawbacks such as an increase in If the support point is configured at the center of the pinion shaft as in this embodiment, the space below the pinion shaft can be used, for example, to create a small chamber for storing the lubricating oil sealed in the gear device that becomes redundant during rotation. , reducing heat loss caused by stirring by large gears, etc.
It can be used effectively.

Most of the traction motor mass and approximately 174 of the gearing mass can be reduced from the sprung mass and transferred to the sprung mass.
